No it might be the same band but the lead singers are totally different. I saw By Jovi a few years ago and the "Jon" was a bit older and had the "these days" hair. He was a really nice guy we chatted to him after the gig.

The new "Jon" however I find to be a complete cock. He doesnt sound anything like Jon and much have thanked his lucky stars when the real JBJ came on stage with him at the fanclub show in 2006.
